I have previously posted a problem with my daughters 92 960 wagon ( 165k ) regarding a strange involuntary change from economy to winter mode while driving under normal conditions. This is usually accompanied by a continuous flashing of the mode light. She had the PMP switch ( replaced 2 yrs ago) checked out on diagnostics but that was "OK". Other diagnostic codes that did indicate error are:
Code 222 Solenoid " 2 operating circuit
Code 113 ( control unit ? )
Code 122 Solenoid " 1)
According to the tech - they have never needed to replace a code 113 control unit. Tech says it must be the solenoid " 2 ( inside the tranny ?) which is a major deal, probably not worth the money although the car is in otherwise excellent body / engine condition.
My concern is the tech ( Volvo specialist ?) does not seem to know exactly what the cause of the problem is and is guessing that you can try the chip first ( $ 350 ) but if that isn't it - then replace the tranny !!!
Why not just eliminate the mode process - she drives in the economy mode anyway. Is this possible as an easy fix ? how ?
"V70" are you out there - your thoughts were the PMP switch, but this tech says diagnostics do not agree. Any thoughts ?
